The architectural heritage of the Kosovo Albanians during Yugoslav rule was shown institutionalised disregard for decades prior to outright conflict at the end of the 20th century. Numerous Albanian cultural sites in Kosovo were destroyed during the period of Yugoslav rule and especially the Kosovo conflict (1998-1999) which constituted a war crime violating the Hague and Geneva Conventions. In all, 225 out of 600 mosques in Kosovo were damaged, vandalised, or destroyed alongside other Islamic architecture during the conflict. Additionally 500 Albanian owned kulla dwellings (traditional stone tower houses) and three out of four well-preserved Ottoman period urban centres located in Kosovo cities were badly damaged resulting in great loss of traditional architecture.
